SEPARABLE BUTTON-SHANK.

Specification of Letters Patent.

Application filed September 5, 1916.

To all whom it may concern:

Be it known that I, VILLIAM H. PIPER, a citizen of the United States,residing at Kansas City, in the county of, Jackson and State ofMissouri, have invented a certain new and useful Improvement inSeparable Button- Shanks, of which the following is a specification.

My invention relates to improvements in separable button shanks.

Gnc of the objects of my invention is to provide a separable buttonshank which may be attached to a garment independently of a button, andto which buttons of various kinds, sizes and shapes may be affixed.

A further object of my invention is to provide a separable button shankwhich may be attached to a garment by securing threads independently ofa button, and in which the securing threads will be protected and notexposed to wear.

The novel features of my invention are hereinafter fully described andclaimed.

In the accompanying drawing, which illustrates the preferred embodimentof my invention,

Figure 1 is a perspective view of my improved separable button shank.

Fig. 2 is a plan view of the same.

Fig. 3 is a side elevation of the same.

Fig. 4 is a vertical sectional view of the same.

Fig. 5 is an enlarged vertical sectional view of the button shank shownattached to a garment and to a button provided with holes for receivingsecuring threads.

Fig. 6 is a view similar to Fig. 5 showing a button, provided at itsinner side with a cloth extension for receiving the securing threads,mounted on the head of the shank.

Fig. 7 is a view similar to Fig. 5'showing the position of the shank tobe the reverse of that as shown in Fig. 5.

Similar reference characters designate similar parts in the differentviews.

The button shank 1 is tubular and is provided in its interior,preferably adjacent to its inner end, with a transverse bridge 2 adaptedto be embraced by securing threads 3 which extend through the goods 4 ofa garment. The threads 3 are entirely encircled by the shank 1, so thatthey are not subjected to wear due to abrasion of a garment or otherarticle which may be affixed to the button carried by the shank.

The inner end of the shank l is provided,

preferably, with a peripheral annular supporting flange 5, which isadapted to bear upon the outside of the goods 4;.

The outer end of the shank l is provided with a head 6, preferablyhaving a concave outer side upon which is adapted to be supported abutton of any desired ordinary kind. In Fig. 5 is shown a button 7 ofthe ordinary type having holes adjacent to its center for receiving thesecuring thread.

The head 6 is preferably provided with a plurality of holes 8. Thesecuring thread 3 may be passed upwardly through one of the holes 8 andthrough one of the holes in the button, thence through another of theholes in the button and through another of the holes 8 in the head,thence back and forth in the manner described until the button has beenfirmly sewed to the shank head 6.

In Fig. 6 is shown another kind of button mounted on the head 6. Thisbutton 9 is of the kind having a central cloth extension 10 on its innerside, the extension being disposed in the concavity of the head 6 con.-centrically of the shank 1 and in position such that the thread 3 may bepassed therethrough and at the same stitch through two of the holes 8 ofthe head. By passing the thread 3 through one set of holes 8 and then inthe opposite direction through another set of holes 8, and back andforth in this manner through the extension 10, the button 9 may besecurely fastened to the head 6.

In case that a button is broken from its fastenings, the shank willstill be firmly secured to the garment, and the head, in some instances,if desired, may be employed to serve the function of the button untilanother button is obtained and sewed thereto.

It will be noted that the annular flange 5 is concave on its inner sideand that the bridge 2 is outside of the plane of the outer edge of theflange. By means of this construction, the securing threads 3 whichembrace the bridge 2 have their inner portions protected by the goods i,which are drawn by thesecuring threads into the concavity of a theflange, as shown in Figs. 5 and 6.

From the above-description it will be seen that the threads 3 whichembrace the bridge 2 are encircled by the shank and are thereby fullyprotected from wear at both the inner and outer sides of the garment.

If desired, the position of the separable the shank or by threadspassing through the holes 8 as shown in Fig. 7

I do not limit my invention to the structure shown and described asmodifications, within the scope of the appended claims, may be madeWithout departing from the pirit of my invention.

What I claim is 1. A. separable tubular button shank having a peripheralflangeprovided With a plurality of holes adapted to receive securingthreads, the flange being adapted to supfiopies of this patent may beobtained for five cents each, by addressing the Commissioner of Yatents"Washington, G.
